Raw vector
CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:HSummary
CVE-2024-9312 is a high-severity Incorrect User Management (CWE-286) vulnerability in Canonical Authd. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Account Manipulation (T1098); ranked at the 20th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-2 (Account Management) and IA-4 (Identifier Management) — see the control section below for these in your framework.

Vulnerability Data
Authd, through version 0.3.6, did not sufficiently randomize user IDs to prevent collisions. A local attacker who can register user names could spoof another user's ID and gain their privileges.

Mitigating Controls (NIST 800-53 r5) AI
AC-2 directly requires defining, assigning, and controlling user accounts throughout their lifecycle, structurally preventing improper user management.
IA-4 mandates authorized management of user identifiers, stopping the creation or retention of unmanaged user identities.
SC-12 requires proper establishment and management of cryptographic keys and material, which directly encompasses correct seeding of PRNGs used for cryptographic purposes.
PS-4 enforces timely disabling and removal of access upon termination, addressing a key failure mode of incorrect ongoing user management.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Directly addresses management of user identities and credentials throughout their lifecycle.
Covers policy-driven definition and review of user permissions and entitlements.
Secure SDLC practices directly enforce correct PRNG seeding during development, though the control addresses many other coding issues as well.
Supports proper user onboarding by binding verified identities to credentials.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Identity management directly governs the full lifecycle of user accounts, preventing incorrect user management.
Access rights provisioning and de-provisioning ensure users are correctly created, modified, and removed.
Responsibilities after termination or change of employment address removal of user access but not ongoing user management.
Privileged access rights assume correct user accounts exist; the control does not manage user creation or removal.
Security testing can detect weak seeding but does not itself prevent the weakness.
Access control policies rely on accurate user management but do not themselves define user lifecycle processes.
